Complete mitochondrial genomes of two gecko species, Gekko hokouensis and Gekko japonicus (Squamata, Gekkonidae)

The Gekkonidae is the second-most-numerous Family in Sauria and widely distributed around the world. In this paper, the complete mitochondrial genomes of two gecko species, Gekko hokouensis and Gekko japonicas, were sequenced. The lengths of the two mitochondrial genomes (G. hokouensis and G. japonicus) are 17 956 bp and 17 769 bp, respectively. These mitochondrial genomes both contain 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes and a non-coding region (control region). The overall base compositions of the H-strand of G. hokouensis and G. japonicus are 32.1% A, 26.7% T, 27.0% C, 14.2% G and 31.6% A, 25.2% T, 28.6% C, 14.7% G, respectively. Phylogenetic analysis showed that G. hokouensis is a sister clade with G. swinhonis. G. japonicus has a close phylogenetic relationship to the clade of G. hokouensis and G. swinhonis.
